World Wide Neuro is an Open Science platform that hosts (and disseminates information on) virtual seminars in the domain of Neuroscience. It started as a natural evolution of the Oxford Neurotheory Forum that had to go online due to COVID-19. WWN is now a well-established entity of its own involving seminar series from many academic institutions and hosts round the world. Recently, we expanded WWN to more scientific domains, like Machine Learning, Open Source, and Psychology.
